Location
Units represented in this manual are intended for indoor use
only. Be sure the location chosen has a floor strong enough to
support the total weight of the cabinet and contents. Reinforce
the floor as necessary to provide for maximum loading. Take
care when moving the equipment that nothing gets pinched
between the unit and stationary objects. Sheet metal edges,
although deburred, could cause cuts in certain situations.
For the most efficient refrigeration, be sure to provide good air
circulation inside and out.
Inside cabinet: Do not pack refrigerator so full that air cannot
circulate.
Outside cabinet: Be sure that the unit has access to ample
air. A minimum space of 3” (7.6cm) at the back of the unit
and 1” (2.5cm) at the top and sides is required to conform to
Underwriters Laboratories’ standards. On undercounter units
it is imperative that the proper air flow be maintained. The
refrigeration system is designed so air will flow under the unit,
over the compressor/condenser area, and out at the top rear of
the unit. Avoid hot corners and locations near stoves and ovens.
Any restriction of the proper air flow outlined
above, total or partial, will void the warranty
on the unit.
Leveling
A level cabinet will perform better because the drain pan will
drain properly, the doors will line up with the frames and the
cabinet will not be subject to undue strain.
All four legs are adjustable. Adjust each leg until the unit is
stable and level left to right. If necessary adjusting the front legs
slightly higher than the rear by about 1/8” (0.3cm) will help the
door remain closed.
If the unit is supplied with casters, no adjustments are available.
Ensure the floor where the unit is to be located is level.
Never stand on the unit! Doing so may result in
bodily injury. They are not designed to hold the
weight of an adult and will collapse if misused in
this manner.
Stabilizing
These models are supplied on casters for your convenience, for
ease of cleaning underneath and mobility.
The unit must be installed in a stable condition with
the front wheels locked. Locking the front casters
after installation is the owner’s responsibility. This
will keep the unit from rolling or tipping.
Plumbing
Self-contained models are standard with a condensate
evaporator. If, for some reason, a unit does not have a
condensate evaporator, or the evaporator fails, the unit’s
drain must have an outlet to an appropriate drainage area or
container.
Moisture collecting from improper drainage can
create a slippery surface on the floor and a hazard
to employees. It is the owner’s responsibility to
provide a container or outlet for drainage.
Electrical connection
Refer to the amperage data, the serial tag, your local code or the
National Electrical Code to be sure the unit is connected to the
proper power source. A protected circuit of the correct voltage
and amperage must be run for connection of the line cord, or
permanent connection to the unit.
A 6’ (1.8 m) long grounded supply cord and plug are provided
with standard units. Simply plug the unit in to begin operation.
The thermostat must be turned to OFF and
the unit disconnected from the power source
whenever performing service, maintenance
functions or cleaning the refrigerated area.
If the supply cord is damaged it must be
replaced before operating this equipment. Do
not connect a damaged supply cord to a power
source. The cord must be replaced by a qualified
service personnel.
Stacked 400 series electrical connection
Models 406 and 407 may be stacked using a stacking
collar, Delfield model 409. In this case two 6’ (1.8m) long
grounded supply cords and plugs are standard. Simply
plug them in to begin operation.
For Cord Connected Units - Risk of Electric
Shock. This equipment has two power supply
cords. Unplug all cords before moving or
servicing this equipment.
